When JEG-3 cells were transiently transfected with this construct and treated with cortisol or its synthetic analogue dexamethasone, a stimulatory effect on the upstream promoter activity was observed. This stimulation was dependent on the cotransfection of a glucocorticoid receptor (GR) cDNA expression vector due to the low level of GR in JEG-3 cells and could be completely abolished by RU486, a glucocorticoid antagonist. Moreover, the cortisol actions could be modulated to a different extent by oestradiol. Thus, since the human placenta contains GRs and the increase in cortisol metabolism near term is regulated by oestrogen, the current findings suggest that cortisol may be physiologically involved in the regulation of GnRH gene expression in the human placenta. ------>tmu_sno=None ------>sno=20795 ------>authors2=Chou CS ------>authors3=Hsu MI ------>authors4=Dong KW ------>authors5= ------>authors6= ------>authors6_c= ------>authors=Chen ZG ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=Chou CS ------>publish_area=0 ------>updateTitle=Glucocorticoids modulate human gonadotrophin releasing hormone upstream promoter activity in transfected human placental cells (JEG-3). ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=1 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=1998 ------>submit_flag=None ------>publish_month=1 |
